Аннотация: The Permian–Triassic magnetostratigraphy of the central East European platform has been updated using evidence fromthe Zhukov Ravine, Slukino and Okskiy Siyezd reference continental redbed sequences. The new data reveal five rather than four polaritysubzones in magnetozone R3P, which thus can be ranked up to orthozone RnP. The upper Permian strata of the Zhukov Ravine and OkskiySiyezd sections contain intervals of anomalous paleomagnetic directions similar to those revealed earlier in roughly coeval rocks fromthe Nedubrovo section in the Vologda region. The anomaly may be of regional extent and may correspond to quite a long (thousands ofyears) span of geomagnetic field stability near the Paleozoic–Mesozoic boundary, which fits the subequatorial dipole field in the first approximation.The paleomagnetic results were used to constrain the position of three new Permian–Triassic paleomagnetic poles of the EastEuropean platform, corrected for inclination shallowing: PLat = 54.8°, PLong = 173.6°, dp/dm = 2.6°/4.0° (Zhukov Ravine); PLat = 47.6°,PLong = 164.3°, dp/dm = 3.0°/4.8° (Slukino); PLat = 52.7°, PLong = 153.6°, dp/dm = 3.7°/5.4° (Okskiy Siyezd).
